WRZ / WRZ 8000
Weather control panels WRZ and WRZ 8000 are especially designed for the use in 230V ventilation systems.
The system can be extended up to 20 ventilation groups by using cutoff relays TRL 8, in which each group is individually controllable via vent buttons and/or room temperature control. Due to the possibility of connecting up to 20 D+H 230V-ventilation drives per group, systems with up to 400 drives can be realized. A central weather function ensures the automatic closing of all ventilation groups in case of strong wind or rain.
